The US relies on China more than any other country for its critical minerals.[1] I wonder how much this plays (or should play) into the current US-China trade war and all its noisy politics right now.
After China, the US is most dependent on Canada for minerals. Canada can't supply everything (lithium comes to mind) but at least that seems to be an alliance the US has a better chance to preserve.
This feels like a MIC protectionist push for mining more than anything. With the massive navy claiming world wide shipping as the defacto world reserve currency is unreliable? Get real.
The number of viable cut off scenarios is vanishingly small - especially if it excludes catasophies that moot the point utterly.
